How snug should the fit between the damper and crank be? I just installed a new 440 Souce SFI damper and I got it on but it took some effort with an install tool and LARGE wrench.

Snug slip fit.


Clean it, if it's Dirty. Oil it, if it Squeaks. But: Don't fix it, if it Works!

They key is for indexing only, the friction of the fit is what keeps it in place. Tight is good.
